Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
 To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
 Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive electronic components.

3.1 Introduction
AMI BIOS has been integrated into many motherboards for over a decade. With the
AMI BIOS Setup program, users can modify BIOS settings and control various system features. This chapter describes the basic navigation of the SOM-4466 BIOS
setup screens.
Figure 3.1 Setup program initial screen
AMI's BIOS ROM has a built-in Setup program that allows users to modify the basic
system configuration. This information is stored in battery-backed CMOS so it retains
the Setup information when the power is turned off.
SOM-4466 User Manual

Turn on the computer and then press <F2> or <DEL> to enter Setup menu.
3.2.1 Main Setup
When users first enter the BIOS Setup Utility, users will enter the Main setup screen.
Users can always return to the Main setup screen by selecting the Main tab. There
are two Main Setup options. They are described in this section. The Main BIOS
Setup screen is shown below.
Chapter 3
3.2 Entering Setup
AMI BIOS
Figure 3.2 Main setup screen
The Main BIOS setup screen has two main frames. The left frame displays all the
options that can be configured. Grayed-out options cannot be configured; options in
blue can. The right frame displays the key legend.
Above the key legend is an area reserved for a text message. When an option is
selected in the left frame, it is highlighted in white. Often a text message will accompany it.

System time / System date
Use this option to change the system time and date. Highlight System Time or
System Date using the <Arrow> keys. Enter new values through the keyboard.
Press the <Tab> key or the <Arrow> keys to move between fields. The date
must be entered in MM/DD/YY format. The time must be entered in HH:MM:SS
format.
